FEARS that baiting dingoes and other wild dogs on pastoral land on mainland Australia will open the door for smaller predators are unfounded, research shows.
Baiting is the most common way of controlling wild dogs to prevent the estimated $48.3 million a year in damage they cause to agricultural productivity.
But some scientists have called for dingo baiting to be banned to protect wildlife, arguing dingoes would keep down the numbers of other predators.
New research from the Invasive Animals Cooperative Research Centre (IA CRC) says current baiting programs in the rangelands do not simply result in more foxes and feral cats.
"It just doesn't happen," says Ben Allen, an IA CRC researcher at Biosecurity Queensland.
The numbers of foxes, feral cats and goannas are the same or even greater in areas where dingoes are left alone compared with areas where dingoes are controlled by lethal means, says a new study published in Frontiers in Zoology.
"Baiting of dingoes in the rangelands kills foxes too and the end result is that there are less mesopredators in places where you bait and baiting might even be beneficial for rangeland wildlife," says Allen, the lead researcher in the study.
In Australia, 1080-baiting is the most widely used method of wild dog and fox control for the protection of livestock and conservation of fauna threatened by predation.
NSW Department of Primary Industries researcher Peter Fleming said the study was reassuring about the ecological outcomes of predator control in pastoral ecosystems but the results don't really help understanding of the wetter, more complex and productive ecosystems nearer the coast.
Another IA CRC project team is investigating the responses of predators, prey and plants to canid control in those ecosystems.
